Just got back from Dynamic Diesel & Bear Alignment in Snohomish, WA. Very impressed.
Quick work (in-and-out in right about an hour), and done right. The alignment guy there is apparently the third generation of the original Bear Alignment owners/founders and has been doing alignments his whole life. He was able to get me to 3.6/3.7 Caster, 0.00/0.00 Toe and 0.00/0.01 Camber. Steering wheel is perfectly aligned.
Silly Les Schwab saying I was maxed out at 1.6 caster.
Driving home, truck felt very stable and the wander is all but gone. There's still a hint, but that's easily explained by crappy, gooved roads and wider tires. I'm more than pleased with the results, and the customer service was excellent. The true testament is that they are this good at 4pm on a Friday.
